ok new fight
1st fight pretty much the same. superman and gladiator get a day to know eachother and what they can do. they have no idea they are fighting thanos the next day
2nd fight superman and gladiator get a day to team up and know each other and they have an additional day to study thanos's powers.
they can only google thanos and find out what he is capable of doing so they know what to watch out for and to be ready. but they cant set up any traps or make any weapons.
3rd fight thanos stands in the middle superman stands in front of thanos 10 feet away. gladiator stands behind thanos 10 feet away and nobody can do anything till punisher gun fires. once he fires BAM they go at it.
also superman and gladiator still get a day to google thanos and plan some moves. can only use their powers.
